EMC2 with parallel robot

The simple way is to just write your g-code by hand otherwise you need cam software to convert your drawings to g-code (usually not free). If you have a list of coordinates you can just copy and paste them in the g-code file after the first G0 or G1 for linear moves.

You can send a g-code file directly to Axis. You might also explore using variables and M100. If you know TCL take a look at the program in the subroutines section or look at my simple g code generators on the wiki for info on how to send a g-code file to Axis.

Sounds like an interesting project, keep us posted on your progress.

My project is to get objects from a mat. I'll locate the objects with a Software that I have made and write the G-code with this software in a file. My problem is how to do EMC2 reading this file that I have created.

You might want to consider bypassing the G-code file, and using emcrsh to send the movement commands. (But I confess I know nothing at all about it)

I will also need to update this file every 10 second for exemple to implement new coordinates. Can I do that with EMC2 ? Will It let me use a file while it's using for reading coordinates ?

One thing that might work (but it is horrible is this

#1 = 1
O100 WHILE [#1 > 0]
O<filename> CALL
O100 END WHILE

Then you ought to be able to write G-code to a file called "filename.ngc" in the PROGRAM_PREFIX directory, and see EMC act on it. (set #1 to 0 in this file to end it).

This is not tested, I am not even sure that you end a WHILE with END WHILE in EMC2 G-Code...
